Hello,

We recently updated our web app to .Net Core 2.0, and we updated all of your tools as well to their latest versions.  However, we noticed that the export to excel functionality that we have for one of our grids started running extremely slow all of a sudden, and we're not entirely sure why.  If we have hundreds of entries that we need to export, when we click the "Export to Excel" button it spends all of its time trying to transfer the data before downloading and eventually the page crashes.  I also noticed that it will try to transfer over 1GB of data which is way too much for what it should be.  We did not have this issue before updating your tools, so we were wondering if something changed with how the export to excel functionality works with your latest updates to it (such as if the syntax for it is different than what it was before)?  We did test the functionality on a small list of items, and it did export immediately.  It's only with when we have hundreds of items to export when this happens.  We checked to see if any of the .Net Core 2.0 updates or anything else new in our code could have affected the speed of it, but we couldn't find anything.

Thanks,

Jason

Hello,

I am using a template within a template and I would like to use DropdownListFor. Although everything is rendered properly and the values are shown correctly, when I click on the right arrow it does not expand the list options. 

Example:

Using PDFViewer and pdfjs processing in my view, the pdf file, once loaded in view the toolbar shows 6 pages, but the pdf content flows outside the containers as one long image, with all 6 pages shown.

Anyway to contain just one page at a time, or keep the content in a container?

Thanks,

MK

Does the TreeList have the ability to create have a dropdown selection for columns similar to the "Categories" on here: 

https://demos.telerik.com/aspnet-core/grid/editing-custom 

I followed everything on the page I believe but I can not get the dropdown to work for the TreeList.

Does the TreeList work that much differently?

hello,

I am using a scheduler with ASP.NET Core 2.2 MVC app.(Example @(Html.Kendo().Scheduler<xxxScheduleViewModel>()

When I create an event, I'd like to change the default field names . For example , Instead of 'Title' , say  'Book event' (see picture)

Is this handled in Schema ? Any examples?

Thanks,

Peter

Hello,

I am working with using a DateRangePicker with the calendar section always open and I have it in a sidebar. The problem I am having is that the calendar portion does not resize to fit the space it should be contained within. The multiselect I have in the same div work as expected and size down when the size of the window goes down but the calendar of the DateRangePicker instead stays the same size and starts to cover other elements on the page. Any ideas on how I could make the calendar resize properly?

Thanks,

Alex

hello,

This probably is not Kendo problem , but I am hoping someone has a suggestion.

I am using Visual Studio 2019 ver.16.1.15 , creating a ASP.NET MVC core 2.2 Application, with , and Cosmos DB datastore. 

Scheduler Events are created in the this controller/action :       .Create(create => create.Action("Create", "Crud"))

Recently I found 19,000 duplicate events, and I am trying to track down the root cause.

Is the controller/action  being called over and over?

Or is Cosmos DB doing something unintended ?

Any ideas?

Thanks,Peter

Hello Telerik,

I am using UI for ASP.NET Core (2019.1.220) and in my .cshtml I'm creating a ListView that I want to be endless scrollable.

As you can see from the attached image, it seems that both the Scrollable method and the ListViewScrollableMode enum are not found.

Am I missing some reference or using directive?

Thank you,

Maurizio
